Introduction

Diagram of Pivot Parts

OVERVIEW OF STEP PROCEDURE

1 Take 4 12 hole tubes. 2 of these are the Leg Cylinder Tubes, and 2 are the quick attach plate tubes.

2 Mount the quick attach plate bottom 3 hole plates. Mount the quick attach plate top 2x3 hole plates. Use only the 2 of the 3 inner holes, as the third hole will be used to mount the leg cylinder tubes. Use 6 of 7" bolts, and use a 2" bolt for the Top Quick Attach Plate Tube. The 2 inch bolt is used to avoid conflict in mounting the angled support.

3 Cut the Angled support from a 24" piece of 1/2"x4" plate.

4 Install the Angled Support.

5 Install the Leg Cylinder Tubes.

    • Step 21

    • Zero - flip pivot upside down using a hoist

    • build cylinder bottom mount plates consisting of one by four whole plate pieces

    • cut bushings four-cylinder bottom mount and bolt cylinder mount one by fours to the pivot part one

    • Cut 7.5 inch 1 inch shaft to size and weld a T handle on it consisting of a piece of 2" x 0.5" rebar

    • place cylinder in position and place shaft through Buesching and cylinder mount and through second Bushing

    • hold in place to where it will be welded put a small spacer underneath the rod and part of the cylinder to fit exactly within The 4 inch cavity of pivot part one.

    • The bushing location should be exactly 1.6 inches behind the & whole of the one by four hole plate, Or right behind the hole So that people can be put in the fourth hole of the one by four hole plate

    • Repeat for the second cylinder

    • Build cylinder rod and mount

    • take a 2 x 3 whole plate and notch out a space on the one and that is two and three-quarter inches from the edges and 2 inches deep.

    • Take a second plate which is an unfinished pivot plate and cut it down to 11 1/2 inches on the long side and cut off 1/2 inch from all sides to make it slightly smaller than the 3 x 2 whole plate

    • weld these two pieces together all around the edges for a solid fit.

    • Weld the 2 inch mounting bushings around the notch exactly 1.5 inches away from the edge of the 2 x 3 plate. Make sure that the spacing between them is exactly 2.25 inches or the width of the rod and cylinder tube. Weld with the shaft in place

    • weld the 2 x 3 gusset plate right in front of the cylinder mount bushings and weld solidly to the plate assembly. Do two of these per mounting plate.

    • repeat for the second cylinder

    • bolt the Rod and mount plate to pivot part two using short bolts. Do this only hand tight.

    • Put in the rod and mounting pin to make sure it fits

    • take off the Rob and mounting plate and put on two pivot plates. For mounting the boom

    • Bolt on the cylinder boom cylinder mounting assembly to the top of that part two

    • Mount the quick attach Finger assemblies on the tractor - at hole 10 on the front loader

  40. Move tractor to the backhoe and put the upper quick attach finger weldment into place on both the right and left-hand sides Of the quick attach and tack into place Add triangular support to side of finger for strength Add triangular support to side of finger for strength

    • Move tractor to the backhoe and put the upper quick attach finger weldment into place on both the right and left-hand sides Of the quick attach and tack into place

    • Add triangular support to side of finger for strength

    • Determine the location of the latch hole for the bottom quick attach part and torch it out

    • Put the bottom quick attach plate weldment into place on the backhoe and tack

    • Move tractor away and finish weld the quick attach plates on the Backhoe
